A newly reformed "tree of life" for anemones revealed an errant branch: It turns out that one of the creatures classified as an anemone is actually the first discovered in a new order of animals, the equivalent of the first member of primates.

A new study finds that certain dogs, just like certain humans, carry a gene mutation that causes albinism — a condition that results in little or no pigment in the eyes, skin and hair.

The ongoing collapse of shark populations has already had far-reaching effects on marine ecosystems. To arrest this trend we need scientific data that effectively inform conservation management. But are we focusing our research effort in the right areas?

Octopuses are not in complete control of their arms, but evolution has devised a clever and simple way to prevent them from getting tied in knots: Something in their skin prevents their own suckers from grabbing on.

An octopus handling its own freshly amputated arm holds it gingerly and avoids grasping the skin, while an octopus handling another octopus' arm grasps the skin easily.

In a chance discovery, scientists found the first images of a dead whale shark and three dead rays on the bottom of the Atlantic Ocean. Though "fish falls" are common, it's very rare for scientists to find these sunken carcasses.

The amazing diversity of sea anemone, stationary animals that typically live on the seafloor or coral reefs and are related to corals and jellyfish, comes to light in stunning images.

Sharks are known for their speed and agility under the waves, but how their jagged skin enables these feats has long mystified scientists.
14 May 2014, 06:00 PM ET
Researchers from the Scripps Institution of Oceanography at the University of California, San Diego, are investigating why elephant seals have high levels of carbon monoxide in their blood.

A new long-necked dinosaur discovered in Patagonia is the first of its kind found in South America. It's also one of the last survivors of its family, and possibly the smallest.

According to the National Climate Assessment, oceans currently absorb about a quarter of human-caused carbon dioxide emissions to the atmosphere, leading to ocean acidification that will alter marine ecosystems in dramatic yet uncertain ways.

A bloom of new jellyfish started appearing in the Gulf of Venice last autumn.

Petrified giant sperm found in small 16-million-year-old organisms called ostracods are the oldest sperm preserved in rock. In many cases, the sperm are longer than the body size of the organisms that created them.
13 May 2014, 07:01 PM ET
Giant sperm preserved in rock in Australia is the oldest of its kind. The sperm belongs to a mussel-like creature, and the new discovery reveals a reproductive strategy reliant on oddly huge components that has been unchanged for millions of years.
